To all whom .it 'may' concern:

Be it known that we, JOSEPH CHANCELE .CHAIX andELm DUH, citizens of theisiana, have invented a new andv useful Centrifugal Attachment forSugar-Driers, of' which the following is a specification.

This invention relates to a centrifugal attachment for sugar driers.

Theobject of the invention is, in a ready, simple and practical manner,to` eliminate the hand work which is at present used in sugar houses andrefineries, to cut 4the dry sugar from the inner sieve and force thesame out of the centrifugal, whereby labor and time will be saved andthe work of drying the sugar greatly expedited.

A further object isto provide an attachment of this character whichshall be4 of such construction that its attachment to a centrifugalalready in use will not require .which when not in use may readily be removed lto a point within convenient reach when again needed.

, With the above and other objects in view,

'as will 'appear as the nature of the inven ltion is better understood,the same conslsts in the novel construction and combination of arts ofacentrifugal attachment for [.sug r driers, as will hereinafter be fullyIn thevaccompanying part o'f this described and claimed.

`held against dropping Referring to ,the drawings, 1

the outer shell of a `centrifugal of any preferred type, 2 the sieve, ,3thel discharge chutes, which are disposed .beneath openings 4 in theimperforate portion 5 at the, enter of the sieve, 6 a polygonal spindlerigid with the portion 5, and 7 a sleeve movable onthe spindle andprovided at its lower endgwith a base 8 arranged normally to close theopenings 4, and at its upper end .with a ulley 9 that is designed to bedriven, bya Nelt,

not shown, actuated from any suitable source of power. y A As usual, theshell is provided withan ,in-

turned flange 10, upon which is boltedthe attachment which consists, inpart,` l.of a

bracket 11 that is secured to the.` flange by bolts 12 so as to 'beremovablewhen, ydesired. Bolted to the bracket are twoverticallydisposed tubular bars `13 whichlpass loosely through orifices in a head14: and have their upper ends connected by a `plate 15 carrying threesheaves 16, 17 and 18:,-the first and .last named sheaves being disposedover the open upper' ends of bars l13.L These sheaves are engaged by arope or chain 19,

the' two ends of which pass. around the shcave 17 in oppositedirectionsand around the sheaves 16 and 18 and have attached to their free endscounterweights 20..'f`The lower end of the rope is secured to an eye 2larranged on the upper end of the heed 145 which latter slides on thebars.

Carried by the head and rigid therewith, is the upper-end of a shaft 22,the lower end of which terminates a short distance above the Hoor of thescreen. shaft are two collars 23 and 24 eahof which is provided with atubular extension 25 and 26 respectively, and these extensions areengaged loosely by a shaft 27 that is stepped -into the extension 26 andis thus Hinged to the'shaft 27 is a curved metallic plate 28, havingse-Secured upon rthev cured to its outer edge a wooden bar 29 that visdesigned to scrape the sugarfromthe screen, wood being employed toprevent cutf. ting of the latter: The plate fisprovide'dl with a seriesof hinge butts 30that 1nter lock with similar butts 31 carriedbyone edgeof a curved plate 32, the two series f )fbut-ts being engaged by theshaft 27. yIn operation l the member 28' constitutes aA cutter, yand-themember 32a sweep, and by these terms these parts will `hereafter bereferred to. In order lever has connected with it one end of a link arm37, rigidly secured to the upper end of 36, the other end of whichconnects with an the shaft 27.. It will be seen by this arrangemovementof the sweep, a stop ment that when the lever 34 is moved toward thehead the cutterwill be brought into contact with the sugar, a reversemovement holding it out of contactwith the sugar. Normally the sweeplies close to the cutter,

being held in that position `by-means of a coiled spring 38, the ends ofwhich are secured in eyes 39 and 40 carried respectively by the cutterand the sweep. The lower end of both of these last named elements has abrush 41 and 42 connected with it inorder t0 sweep the bottom ofthecentrifugal free from the sugar. To limit the outward 41 is provided,which is rigid 'with the shaft 22, as clearly shown in Fig. 4. l

-It will be observed b' reference to Fig. 1, that the attachment hasnoother support than the flange 10 of thel shell, andfin order .to preventthe latter from sagging from the weight of the attachment a brace .43 isemployed, one end of which is bolted to the side ofthe shell, and to theotherend to the bar 13, and 'this arrangement will 'positively hold theattachment in vertical, and thus operative position and insure propercontact between the scraper and the screen.

In operation when a fresh chargeof massecuite is to be supplied to thescreen, the head 14 is raised, thereby lifting the cutter and sweep outof the screen, and the sleeve is lowered to cause its base to close theopenings 4, and the driving belt, (not shown) is positioned on thepulley 9, it being understood that the belt is removed each time thesleeve is raised. The centrifugal is now started and continues to rununtil all of the liquid is expelled and the dried sugar has accumulatedon the walls and bottom ofthe screen.- The sleeve "7 is now raised tothe and the shafts toxvhich they are attached, so'

that no means need be employed for holding the attachment out'of thescreen. The een trifugal is again started and the operator swings thelever 34 to one side thereby bring-- ing the cut-ter into engagementwith the I' walls of the screen and as soon as the sugar ceptacle. Vhenthe operation is completed the attachment.. is again raised, the sleevelowered and the operation of drying again repeated.

1We claim: l

l. An attachment for centrifugal sugar driers comprising a'stationarycutter having a scraper arranged at one edge, a -sweep having-pivotalrelation to the cutter, andv means for holding the sweep normally infolded" position relative tothe cutter.

i v 2. An attachment for centrifugal sugar .driers comprising a bracket,bars supported thereby, a head slidable o n the bars, ,v aI shaft rigidwith vand depending from the head, a second shaft supported for rotarymovement by the first shaft, a fixed cutter and a hinged sweep supportedby the second shaft, and means for rotating the second shaft to move thecutterl toward the walls of the screen.

shaft rigid with and depending-from the head, a second shaft supportedfrom the first shaft, a fixed `cutter' and av movable sweep carriedl bythe second shaft, and a `shaft rigid with and depending from the head, asecond shaftf supported by the first shaft, a xed cutter and ahingedsweep carried by the second shaft, means for imparting 2t rotarymovement to the second -lever operatively connected with the secondshaft-whereby to move the cutter from the screen, and counterbalancingmeans connected with' the head.'

5. An attachment for vcentrifugal sugar driers, comprising a bracket,tubular bars secured at their lower ends to the bracket, a plateconnecting'the upper ends of the bars, pulleys` carriedy by the plate,-ropes passing around the pulleys and carrying weights at their freeends disposed-within the bars, a head slidable on the bars ,and to whichthe lower end of the rope is secured, a shaft rigid with and dependingfrom the head, a second shaft supported by the first Shaft, axed cutterand a; hinged sweep caras our own, we have hereto axed our sigriedby thesecond shaft, the sweep .being natures in the presence of two witnesses.
